Bangles are traditionally rigid bracelets which are usually made of metal, wood, glass or plastic. These ornament are worn mostly by women in the Indian subcontinent, Southeastern Asia, Arabian Peninsula, and Africa. It is common to see a bride wearing glass bangles at weddings in India, Bangladesh, Pakistan, Nepal, Sri Lanka and in other Asian countries. Bangles may also be worn by young girls, and bangles made of gold or silver are preferred for toddlers. Some men and women wear a single bangle on the arm or wrist called kada or kara.

In Sikhism, the father of a Sikh bride will give the groom a gold ring, a kara (steel or iron bangle), and a mohra. Chooda is a kind of bangle that is worn by Punjabi women on their wedding day. It is a set of white and red bangles with stonework. According to tradition, a woman is not supposed to buy the bangles she will wear. Firozabad, Uttar Pradesh is India's largest producer of bangles.

Bangles made from sea shell, copper, bronze, gold, agate, chalcedony, etc. have been first excavated from multiple archaeological sites throughout the Indian subcontinent. A figurine of a dancing girl wearing bangles on her left arm has been excavated from the Mohenjo-daro archaeological site (2600 BC) in modern-day Pakistan. Other early examples of bangles in ancient India include copper samples from the excavations at Mahurjhari, followed by the decorated bangles belonging to the Mauryan Empire (322–185 BC) and the gold bangle samples from the historic site of Taxila (6th century BC). Decorated shell bangles have also been excavated from multiple Mauryan sites. Other features include copper rivets and gold-leaf inlay in some cases.

Bangles are circular in shape, and, unlike bracelets, are not flexible. The word is derived from Hindi bungri (glass). They are made of numerous precious as well as non-precious materials such as gold, silver, platinum, glass, wood, ferrous metals, plastic, etc. Bangles made from sea shell, which are white colour, are worn by married Bengali and Oriya Hindu women. A special type of bangle is worn by women and girls, especially in the Bengal area, commonly known as a "Bengali bangle", which is used as a substitute for a costly gold bangle, and is produced by fixing a thin gold strip (weighing between 1–3 g) is thermo-mechanically fused onto a bronze bangle, followed by manual crafting on that fused gold strip.

Bangles are part of traditional South Asian jewellery. They are sometimes worn in pairs by women, one or more on each arm. It is also common for women to wear a single bangle or several bangles on just one wrist. Most Indian women prefer wearing either gold or glass bangles or a combination of both. Inexpensive bangles made from plastic are slowly replacing those made by glass, but the ones made of glass are still preferred at traditional occasions such as marriages and on festivals. Bangles are the signs for traditional women and girls. Bangles play a very important role in various India dance forms. Some of dance forms include bangles striking to each other a tone of the music.

The designs range from simple to intricate handmade designs, often studded with precious and semi-precious stones such as diamonds, gems and pearls. Sets of expensive bangles made of gold and silver make a jingling sound. The imitation jewellery tends to make a tinny sound when jingled.

There are two basic types of bangles: a solid cylinder type; and a split, cylindrical spring opening/closing type. The primary distinguishing factor between these is the material used to make the bangles. This may vary from anything from glass to jade to metal to lac and even rubber or plastic.

One factor that adds to the price of the bangles is the artifacts or the work done further on the metal. This includes embroidery or small glass pieces or paintings or even small hangings that are attached to the bangles. The rareness of a color and its unique value also increase the value. Bangles made from lac are one of the oldest types and among the most brittle. Lac is a resinous material, secreted by insects, which is collected and molded in hot kilns to make these bangles. Among the recent kinds are rubber bangles, worn more like a wristband by youngsters, and plastic ones which add a trendy look.

Normally, a bangle worn by people around the world is simply an inflexible piece of jewelry worn around the wrist. However, in many cultures, especially those from Indian cultures and the broader Indian subcontinent, bangles have evolved into various types in which different ones are used on different occasions.
